I'm Just Sayin...

recently I have been hearing people say someting that has struck me funny. When someone is having a convo and they are either criticizing something or questioning the integrity of a particular subject, the close the convo by leaving an implying statement, "I'm Just Sayin..." Well, I have been looking at this statement and it appears to me that it may just be "sayin", I don't want you to think I'm saying this or I really don't know if this is true. Soak up this scripture today...I'm deffinately gonna...."stop sayin".

James 5:12

But above all things, my brethren, swear not, neither by heaven, neither by earth, nor by any other oath; but let your "Yea" be yea, and your "Nay" be nay, lest ye fall into condemnation.
